RE: CARGO SPEAKER 2002 SUBURBAN
This is a small space to work with. I pushed in the metal cover of the gas filler tube(making sure that it was still far away from gas tube).without doing this you will probably need a small depth woofer. I then made3templates of the curved surfaces bracketed them in and sealed all airgaps with foam gap filler. Itworks very well. Oh ya I have a 10" sub in there. I am planning on changing it to a dual 10" isobaric enclosure. I will post some pics on here for you to see. You could always use fiberglass which would be a better way to make the back of the enclosure.
